Abstract
Background and Aims: The accessory obturator nerve (AON) often innervates the hip joint and adductor longus. The AON is present in 10-30% of patients, and thus it is clinically important that it is also considered during obturator nerve (ON) blockade. The aim of the study is to identify the incidence of accessory nerve.
Materials and Methods: The study was performed on 23 cadavers (46 body-sides) and the AON beginning from the lumbar plexus was observed.
Results: Throughout the dissections, the AON was detected on five sides (10.8%).
Conclusion: Owing to its anatomical structure, the AON can be easily accessed during classical ON blockade. Further clinical studies are needed to investigate if supplementing ON blockade with AON blockade might improve the clinical efficiency and quality of the blockade.
Keywords: accessory obturator nerve, lumbar plexus, nerve block.
